What is a syphilis dbs screening for antibodies? is this an accurate test? referring to home finger poke send to lab testing?

DBS means dry blood spot. The test usually done is an EIA test, which is highly accurate but takes up to 6 weeks to become positive. If negative more than 6 weeks following the last possible sexual exposure, it is 100% proof you do not have syphilis.

In one study in Europe it was a very highly accurate test over 80% sensitivity and specificity
